The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. GPS works in any weather conditions, anywhere in the world, 24 hours a day. There are no subscription fees or setup charges to use GPS.
GPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. GPS receivers take this information and use triangulation to calculate the user's exact location. Essentially, the GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. The time difference tells the GPS receiver how far away the satellite is. Now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map.
UCView Digital signage technology allows users to define playlist depending on a geographic area. UCView player receives a signal from satellites and continuously provides information such as location, speed, direction, and time. With EZGPS module, the UCView digital signage player will play different playlists according to the location of the player. Network manager can now define playlist and ads according to the location of the player.
UCview delivers the most easy to use user web based interface EZGPS module, allowing you to define your ads campaign by geographical location. Therefore the player will dynamically change the loops according the location of the vehicle. Additionally EZGPS allows you to trigger a specific ad in an exact vehicle location.
